It would be nice to find someone around my own age. Then we could go to the same "school" together."

She had finally ran away from home, so it was time to have tons of fun.  Like doing a dare at an outdoors school's rally.

There were so many things she wanted to see and try out. No matter how much time she had here, it wouldn't be enough.
